DOORCZ-IECK, AUTOMATIC LATCH, AND NIGHT HOOK.

Application filed September W, 1927.

The object of my invention is to provide a door check, automatic latchand night heck of simple, durable and comparatively inexpensiveconstruction.

Another object of my invention is provide a door check wherein the dooris positively checked when closed violently and caused to rebound untilmotion has been slowed down where it will close gently, the

check itself operating to close tne door as soon as its motion has beensufiiciently slowed down. I

Still a further object is to provide pair of members, one mounted on adoor jamb and the other on a door, which members coact with ea en otherfor accomplishing the purpose set forth in the last object.

Still a further object is to provide an arm having a bumper rollerthereon which arm is resiliently held in either of two positions, onebeing a position where the check mechanism is set and the other being aposition wvhere it is not set and where it serves to hold the door inclosedposition.

Still av further object is to provide means on the door for engaging thebumper roller and causing it'to move from a set to a non set positionand further means for preventing movement toward non-set position except30 when the door closes gently;

Still a further object is to provide a night hook on my latch whereby itmay be locked when so desired.

With these and other objects in view my invention consists in theconstruction. arrangement and combination of ti various parts of mydevice, whereby the objects contemplated are attained, as hereinaftermore fully set forth, pointed out in my claims,,and-illustrated in theaccompanying drawings, in which:

Figure 1 is a front elevation of one member of my door check showing thebumper roller in set position.

Figure 2 is a front elevation of the other member used in myconstruction which coacts with the member illustrated inFigure 1.

Figure 3 is a side elevation of the member illustrated in Figure 2 andlooking in the direction of. the arrow' Figure 4: is a sectional viewtaken on the lines 4-4 of Figure 1; and

Figures 5 and 6 are views similar to Figure l showing the parts of thecheck mecha nism in different positions.

Serial No. 222,347.

On the accompanying drawings I have used the reference character A toindicate generally the 'member of my door check structure which isattached to the door jamb 10. The reference character B indicates theother member which is attached to the door frame 12.

The member A comprises a pair of attaching ears 1% which may be securedto a spacer block 16 which in turn is secured to the door jamb 10.Coimter sunk wood screws are preferably used for this purpose. The cars1% are bent at right angles to form top and bottom members 18 and 20. Afront cross member 22 serves to connect the top and bottom 18 and 20 forforming a rigid member to support the mechanism of the door check. Theends of the top and bottom 18 and 20 extend toward each other asindicated in dotted lines in Figure 1 whereby they form a slot 24.

Pivoted to rivets 26 or the like is an arm C comprising side members 28,a cross connecting member 30 and a flange 32.

A rivet 29 extends through the arms 28 and has rotatably mounted thereona wheel 33. The wheel 33 has on it a resilient bum-per roller 31 ofsuitable material such as rubber. The flange 32 is connected by a spring3% to a rivet or the like 36 extending from the top to the bottom of themember A.

The member B comprises a pair of attaching cars 38 which may be securedto the door frame 12. A cardboard shim 4.0 is inserted between themember B and the door frame 12. The cars 38 are bent to form top andbottom members 40 and 42.

For covering the front and sides of the member B and thereby forming asocket I provide a strip of metal comprising the curved portion 44 and acomparatively fiat portion 16 extending between the cars 38. A portion48 of the strip extends beyond the cars 38 and is provided with adoubled under bead 50.

A rivet or the like 51 extends from the top 40 to the bottom 42 of themember B for holding the parts in assembled position and this ivet has afurther object as will be later disclosed in the specification.

A night hook D is provided with ears 52 which extend through openings54% in the top and bottom 40 and 42 of the member B. The hook I) is inthis manner pivoted to the member B and is provided with a hook portion56 s LEM adapted to engage the edge of the cross front member 2:2 of themember A and be positioned in the slot 2% as illustrated in Figure l.This hook may be utilized when it is desired to lock the door for thenight.

Practical opera-Z5092.

Figure 4e illiiistrates the check mechanism oi. my structure as when thedoor closed. The hook D is illustrated as being hooked for the purposeof locking the door in closed position. This hook may be unhooked asillustrated in Figures 5 and When the door 12 is opened as indicated bythe arrow 58, the socket tori-lied by the strip of metal ltl will movethe bumper roller 31 to the position illustrated in lfigure In thisposition the sln'ing i so l acro1-ts the center oi? the rivets w-ierebythe roller 31 will be held in this pee on igu-re by the spring 3i. Thissets the roller ill position to be actuated'by the door wh n closed.

hen the dooris vi ily closed as illustrated in F'g'ur the head 50 willengage the roller fill i he; the arm Clo move in the direction of tnearrow (it); Zhc spring 34 will then have passed across the pivot center26 whereby the roller 31 is caused to enter the socket formed in themember 15. However, violent closing of the door produces enough movementof the door in the direction of the arrow to cause the rivet 51 toengage the roller 31 as illustrated in dotted lines in Figure 5 and theroller is caught between the curved portion :8 of the socket member Band the rivet 5-1 thereof and its further movement in the direction ofthe arrow 60 is prevented. The resiliency oi the rollertll there uponacts to cause a rebound ot' the door 12 and in rebounding, the edge 64of the socket member B will again set the roller 31. This will continueuntil the motion of the door 12 has been su'tliciently checked to allowthe roller 31 to pass the rivet 5i before the roller can. be caughtbetween the rivet and the bead. 50. This positi-on'is il' trot-ed inFigure (l and the arm C will continue to move in the directii-n-i of thearrow (50- whereby it engages in the socket of the member 13 and thespring 34- tends to close the door and maintain it in closed position.

From the foregoing description it will be obvious that I have provideda'device which actually checlie the movementof the door and causes it torebound until its momentum has been reduced to a point where the doorwill not slam when allowed to close. i

In operation, it a person gently closes the door the roller 31 willimmediately enter the socket member 16 and maintain the door closed butviolent closing of the door will causea re'bound and the number ofrebounds will depend on the violence with which the door has beenclosed.

It will be obvious'that my check can be used on all types of doors andwill accomplish the same result. I have illustrated it as being attachedto a screen door but I do not wish to be limited to its use on screendoors only.

Some changes may be made in the construction and arrangement of theparts of my device without departing from the real spirit and purposeoi? my invention, and it is my intention to cover by my claims, anymodiiied forms of structure or use or mechanical equivalents, which maybe reasonably included within their scope.
